Application filed August 17, 1912. Serial No. 715,635.

T0 all whom t may concern:

Be it known `that I, JEAN ADAi/LGEORG IFFERT, of 'Frankfortx-.on-the-Main, Germany, a subject of the King of Prussia, have invented certain Improvements 1n `Pulling-Over Machines, of which the following description, in `connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like `parts inthe several gures.

` This inventionrelates'to pulling over machines and is herein shown as embodied in a machine of the type shown in United States Letters Patent No. 663,7 7 7, granted December 11, 1900, on application of R. Mc- Feely. In the use of machines of this type there are numerous occasions for taking ay shoe out of the machine without fastening it as, for example, because the operator gets the shoe in the machine incorrectly or some peculiarity of the work develops after the upper has been strained which requires; attention before completing the operation. Each-gripper must be released before the shoe can be taken out and to do this the operator reaches into the machineV with a screw driver or other tool and .engages the tripping devices, the commercial grippers being made with tripping devices substantially like those shown in United States Letters Patent 1,030,264, granted yJune 18, 1912. By this procedure the grippers which are holding the upper under tension are freed one at a time and when the first side gripper is released the other' one draws the upper transverselyy about the last, pulling it out of shape and sometimes permanently inj uring it.

The object of this invention is to provide conveniently operating means by which a plurality of grippers of this machine including both the side grippers, can be released The machine comprises two grippers engaging the upper at each side of the shoe and supported from levers 2, 2, and one gripper engaging the upper at the end of the toe and suspended from a lever 3. The levers 2 and 3 extend back to a fulcrum and from thence to a yielding connection with cams operated by power. Through the yielding connections the levers raise the operating bars 168 of the grippers which, as described inv the later of said patents, first effect closure of the gripping jaws and then lift the grippers to pull the upper at the end and sides of thelast, after `which the machine comes to rest and then, after such adjustments of the upper as may be required and can be made with the shoe in the machine, the machine is restarted-and caused to overdraw and to fasten the upper, the grippers being released by the incoming of the tackers which strike and operate the trippers 204.

To the machine as so constructed there is added in accordance with this invention a gripper releasing mechanism. Upon pivot studs 10 projecting from the machine frame is fulcrumed a lever attachment 12 in the form of a yoke, the cross bar of which carries two arms 14, 15 that extend forwardly and have rolls 16 on their front ends. The arm 15 carries two rollers which are arranged to engage respectively the one side gripper lever 2 and the toe gripper lever 3 while the roller on the arm 14 engages the i other side gripper lever 2 as shown in F ig. 2.

To the lever attachment 12 at one end is securely fastened the operating arm 20 which projects forwardly and upwardly into convenient position to be engaged by the right hand of the machine operator. A friction clasp 22 of the knife switch type may hold the lever attachment normally in an upraised position at or above the upper limit of the levers 2, 2, 3. If a shoe is found when the machine stops with the upper under tension to be in such condition as to require that it be taken out of the machine without fastening, the operator can pull down the lever 20 with his right hand while having his left hand free to catch the shoe when it is released. The downward actuation of the lever attachment lowers the grippers, the yielding connection of levers 2, 2, 3 with their power operating cams permitting this, toward and substantially to their starting and desire to secure by Letters Patent of the United States l l. In a pulling over machine having' a plurality of grippers arranged to engage an upper at opposite sides of a last and power operating mechanism to cause the grippers to seize the upper, pull it, and then come to rest holding the upper undertension for examination; updraw levers extending from vfront to back of the machine and fulcrumed between their ends, 'and means arranged above the shoe to be engaged and operated by one hand of the Workman While the other is free to receive the shoe and having operative connections With both said updraW levers between their fulcrum and the 'side' grippers to disconnect them simultaneously from the shoe.

2. In a pulling over machine the combina-A pivotally nrounted above- 'the levers2, 2,3

and havingarnsf'to engagesaid levers and an operating bari2'0i bylvvhich to depress all the npdravv 'levers together.

3. In a pulling over machine the combination vvit-h the yieldingly Vactuated updraw levers and-the side grppers connected there- With, of a lever having separate arms eX- tending over the updravvileves, .meansfor retaining the lever normally upraised, and a hand barby which said separate armsmay be caused to depress the kupdraiv levers and release' the side simultaneously. In testimony Where'ofI have signed my name to this specification in the presence of tvvo subscribing Witnesses. Y
